-2x-y=-5 In slope intercept form please! :)
schepotkina [342]

Answer:

-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>

Step-by-step explanation:

-2x - y = -5

first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.

-y = -5 + 2x

divide by -1 on the whole equation

y = -2x + 5 is your answer.

14 times a number decreased By eight is 22 Increase by 20 times The same number
kotegsom [21]

Answer:

14x - 8 = 22 + 20x

x = -5

Step-by-step explanation:

Let "the number" be represented by x

Take each part of the statement and translate into algebraic form

"14 times a number" 14x

"decreased By eight" -8

"is" =

"22 Increased by" 22 +

"20 times The same number" 20x

Put the equation together. Solve for x by isolating.

(

14x - 8 = 22 + 20x

14x - 8 - 20x = 22 + 20x - 20x Subtract 20x from both sides

-6x - 8 = 22

-6x - 8 + 8 = 22 + 8  Add 8 to both sides

-6x = 30

-6x ÷ -6 = 30 ÷ -6  Divide both sides by -6

x = -5

(-2÷3)^-3 ÷ x = (9÷8)^-2​
ycow [4]

Answer:

- 3⁷/2⁹

Step-by-step explanation:

  • (-2÷3)⁻³ ÷ x = (9÷8)⁻²
  • -(2⁻³)×3⁽⁻¹⁾ˣ⁽⁻³⁾ ÷ x = (3²)⁻²×(2⁻³)⁻²
  • -2⁻³×3³÷x = 3⁻⁴×2⁶
  • x = -2⁻³×3³ ÷ (3⁻⁴×2⁶)
  • x = - 2⁻³⁻⁶×3³⁻⁽⁻⁴⁾
  • x = -2⁻⁹×3⁷
  • x = - 3⁷/2⁹
